Thanks for all your tutorials!
For this specific case, aren't we suppose to use the small table of the normal distribution which is usually given one page after the common tables?
I am not sure though, that's why I ask.

@papasoteriou They are called the inverse normal tables. They can often be very limited in what they offer. You don't have to use them, it's up to you. You can work just as well from the main tables.
